Abstract: A manually operable hydraulic selector valve includes a plurality of two-way spool valves which are normally closed and are selectively shiftable individually or in pairs by a joy stick operator to open positions whereby motive fluid can be delivered to a given instrumentality such as the jack cylinder of a construction crane outrigger arm. The joy stick carries a conical disc which cammingly engages drive pin extensions of the individual spool valves. A positive stop for the conical disc is afforded by contact of the disc with the mounting plate of the selector valve. The selector valve is employed with an associated two-way directional control valve.

Abstract: A support assembly for luggage comprises a base plate adapted to be attac to a suitcase, for example, and a support unit, including a caster or runner, that is removably attached to the base plate. The base plate has opposed channels along its longitudinal edges into which the support unit is inserted longitudinally. A stop at the trailing end of the support unit limits insertion of the support unit into the channels, and a latch at the leading end of the support unit prevents unintentional withdrawal of the support unit from the channels.

Abstract: Combination locks employ dial-driven rotary elements that must be turned to predetermined position to open the lock. Each rotary element has a periphery that is circular except for a notch that mates with a ridge portion on cooperable means when the corresponding dial is "on-combination." The cooperable means may comprise a bolt that pivots or slides, for example.

Abstract: A key-actuated padlock comprises a shackle, a case to receive the shackle d a flat, substantially U-shaped spring within the case. One leg of the spring serves as a bolt to restrain the movement of the shackle and the other leg serves as an ejector, urging the shackle out of engagement with the bolt leg. The bolt leg is formed to receive a key to unlock the padlock.

Abstract: Normal operating fluid pressure is applied behind a brake release piston in a first pressure chamber in the brake assembly. Variable operator control fluid pressure is applied in a second chamber of the assembly behind a brake applying piston which opposes the brake release piston in the assembly. A dry chamber for stator and rotor discs of the brake lies between the two pistons with a skirt of the brake release piston surrounding the discs and engaging a pressure plate forming the endmost stator disc adjacent to the brake applying piston. Brake applying springs are intervened between the pressure plate and brake applying piston to impart to the disc brake a fail-safe capability as well as a brake "on" condition when the system is depressurized.

Abstract: A device for mounting a handle on a luggage case or the like includes a s having a pair of posts spaced apart on opposite ends of a mounting base. Between the posts is an opening through the stud sized to pass the end of a handle. The stud has a slot which extends perpendicular to the base on opposite sides of the opening into the interior of the posts. An L-shaped pin passed through a hole in the end of the handle is held closely captured in the slot to connect the handle to the stud.

Abstract: A pair of combination locks is employed to hold the lid of a luggage case cked closed, with a left-hand lock operating as a mirror image of a right-hand lock. Principal parts of the locks, including improved dial-indexing springs (but not the dials) are interchangeable. The dial-indexing springs cooperate with the dials of left-hand and right-hand locks in the same manner, so that all of the dials have the same action.

Abstract: A clip for securing a valance to a luggage shell encompasses the edge of shell and includes means for biting into the shell to securely attach the clip to the shell, and a pair of members formed for abutting engagement with inner shoulders on both the inner and outer flanges of the valance to oppose forces tending to separate the valance from the shell.

Abstract: A coin chute adapted to receive interchangeable coin slides. One type of slide may have one or more coin sockets fitted with one or more knock-out plugs to accommodate differently sized coins in each of the sockets. Another type of slide has either one, two, three or four open coin sockets of different sizes.The chute carries a blocking device with a plurality of sizing dogs biased against the coin slide. The sizing dogs are adapted to engage with the coin receiving sockets of the slide to jam continued projected movement of the slide in the absence of predetermined sized coins therein. The position of the dogs relative to the sockets of the slide and the spacing between the dogs is pre-set to similarly engage with differently sized socket openings of replacement slides without further adjustment of the sizing dogs to permit interchangeable use of coin slides whereby the coin chute is operable to accept a variety of differently sized coins and coin combinations by changing slides.

Abstract: A pair of safety stop blocks are welded to opposite sides of the fly section of a construction crane boom. The stop blocks have slide passages to receive the branches of a boom extension or load cable which is looped around an arcuate saddle near the base of the fly section. A pair of stop buttons are swaged to the extension cable branches between the saddle and the two stop blocks and are normally spaced somewhat from the stop blocks to allow the cable to seek an equal loading position around the saddle. The stop blocks carry cable retainer elements near the tops of the slide passages to prevent the escape of the cable therefrom. Should the extension cable fail in any region thereof under load, at least one swaged stop button will be engaged by a stop block of the boom fly section to positively arrest its retractive movement before any damage can occur.

Abstract: The invention is a temperature probe including an elongated electrically conductive housing having one closed end and one open end. Electrically connected to the inner surface of the closed end is one lead of a thermistor, the second lead of which is connected to the inner conductor of a coaxial cable extending into the open end of the housing. The outer conductor of the cable is electrically connected to the housing near its open end in such a manner as to compress the cable within the housing and induce longitudinal deformation thereof. The compression of the cable within the housing insures that the first thermistor lead is in intimate contact with the closed end of the housing when an electrical connection is made therebetween, preferably by a heliarc welding operation.

Abstract: A safe deposit box nest includes an outer housing into which are assembled a number of sheet metal partitions and shelves to form compartments. In order to eliminate the need for individually fitting each compartment door, each such door is hinged to and strikes against posts formed by extruded members such as aluminum attached to the front of the partitions. To the same end the forward edges of the shelves are disposed between the posts and doors and are folded rearwardly upon themselves and compressd to form shelf edge portions of uniform thickness. Finally, the nest is constructed in a manner which reduces welding to a minimum and helps insure accurate and uniform compartment openings to which the doors are applied.

Abstract: A disc brake primarily for use in a power transmission train between a drive motor and a gear speed reducer features a standardized compact and simplified hydraulic module containing a single piston and a coacting floating cylinder head and an adjusting collar to regulate the movement of the piston. The standardized module is compatible with and operationally connectable to a variety of brake disc assemblies of differing size and torque arresting capacity. The disc brake is biased "on" by constantly acting spring means behind the piston in the hydraulic module when the hydraulic system is depressurized. The brake also possesses a fail-safe capability and has a very desirable "soft feel" during operation due to hydraulic cushioning between the piston and floating cylinder head.
